The study points the way to a wide range of real-time X-ray studies of gas-based chemical reactions that are vital to biological processes. | |
Could we one day control the path of lightning?Lightning dart across the sky in a flash. And even though we can use lightning rods to increase the probability of it striking at a specific location, its exact path remains unpredictable. At a smaller scale, discharges between two electrodes behave in the same manner, streaking through space to create electric arcs where only the start and end points are fixed. How then can we control the current so that it follows a predetermined path? Professor Roberto Morandotti and his colleagues have discovered a way to guide electric discharges—and even steer them around obstacles—through the clever use of lasers. This scientific breakthrough was published on June 19, 2015, in Science Advances, the new open-access journal from the prestigious editors of the international journal Science. |

Fungi get the green light: Chemical basis for bioluminescence in glowing fungi uncoveredFoxfire, the greenish light given off by special fungi in the dark of the forest, was once regarded as magic. Today we know that it comes from bioluminescence, like the glow of a firefly. A team of Russian and Japanese scientists has now unravelled the previously unknown chemistry responsible for the glowing fungi. As they report in the journal Angewandte Chemie, the luminescence of many, if not all, fungi is based on the antioxidant hispidin. A hydroxylase enzyme converts the hispidin to a substance that glows when it is further oxidized by another enzyme. | |

Tuberculosis bacteria hide in the low oxygen niches of bone marrow stem cellsA new study from the Forsyth Institute is helping to shed light on latent tuberculosis and the bacteria's ability to hide in stem cells. Some bone marrow stem cells reside in low oxygen (hypoxia) zones. These specialized zones are secured as immune cells and toxic chemicals cannot reach this zone. Hypoxia- activated cell signaling pathways may also protect the stem cells from dying or ageing. A new study led by Forsyth Scientist Dr. Bikul Das has found that Mycobacterium tuberculosis (Mtb) hijack this protective hypoxic zone to hide intracellular to a special stem cell type. The study was published online on June 8th in the American Journal of Pathology. | |
